I Was Thrown Into an Unknown Manga

"'Scrambled Love', a hit Japanese rom-com manga with over 10 million copies sold.
I possessed the body of an extra, Kim Yu-sung, in a manga I have never even read.

But this guy... turns out he's a massive otaku.
To live a peaceful life without raising suspicions, I decided to play the role of the otaku extra in this rom-com.

But why are heroine clichés triggering around me?
And it's not just one person. This is not going to be easy."
